19 Trouble shooting
Diagnosis
Possible reason
Corrective action
Indicator window
steamed
- Indicator cover damaged
- Indicator sealing damaged
- Cable gland not tightened
- high temperature differences
- aggressive ambient atmoshpere
- change indicator cover
- tighten cable gland
- indicator with pressure relief
- install rinsing connection for N2 gas
Indicator cover untight
- indicator sealing damaged
- change indicator cover
- fasten indicator cover screws
Indicator window icy
- ambient temperature too low
- install N23 rinsing connection
- change to high tem. distance housing
Instrument shows wrong
measuring values
- calibration does not meet process
conditions
- pointer de-adjusted
- review operating conditions, on deviations new
calibrations from manufactuer is recommended
- re-adjust pointer (RP on meas. scale)
No reaction on pointer
despite flow
- pointer is behind the stopper ( RP)
- float is sticked
(pollution)
- remove cover, re-adjust pointern
- remove instrument from process and clean float
and all inner parts carefully
- if sticking parts in the process use of magnet filter
recommended
Float is sticked
- pollution / residues in the process
- Measuring pipe damaged
- gas or liquid damping system damaged by
the process
- remove instrument from the process and clean
carefully
- resend the instrument to the manufacturer for
evaluation
Pointer indication is
pulsating
- Inlet pressure too low
- increase inlet pressure, instrument for recalibration
back to manufacturer (gases) or
- use of instrument with low pressure loss
- re-equip with double turbulent flow damping
- locate valves, gate valves etc. after the instrument
Electrical equipment e.g.
transducer, limit swithes
without function
- wrong wiring
- defective el. parts
- check wiring diagram acc. instruction manual
- change el. parts ( e.g. limit switches ) or sent the
instrument back to manufacturer
Un-known
Sent the instrument back to the manufacturer and
include a detailed failure description

NOTE
:
When ordering spare parts please always mention the serial number of the instrument.
If the float is being removed we recommend a new calibration of the instrument always. Without new calibration additional
measuring errors must be considered.
For further instruction on spare parts please contact the Heinrichs Messtechnik GmbH service department
